This invention relates to a stopper or closure for receptacles, more particularly of the insulated type, as for example, those jugs and other receptacles in common use for keeping foods or liquids hot or cold.

Among the objects of thisinvention'is to provide a stopper, or closure oi the class re{ ferred to above having a smaller stopper incorporated therein, whereby upon removal of the latter liquid contents of the container can be poured therefrom Without the necessity of removing the entire closure.

A further object of this invention is to provide a closure or stopper of simplified and more, economical construction, of increased efficiency and ease in manipulation.

A further object is to provide a stopper or closure, insulated at that portionwhich entersthe opening of the receptacle, and of such construction that its more important parts can be readily stamped out by dies and assembled quickly and'easily.

A still further object is the provision of a gasket of rubber, or the like, that will seat itself against the upper edgeof the neck of the container to which the stopper or clo sure is applied. v V

A further object is to provide a stopper or closure so constructed as to reduce to the minimum thechange in heat condition of I the contents of the receptacle when'a portion of the contents is beingremoved therefrom.

Further objects, advantages andcapabili ties will later more fully appear.

My invention further resides in the com-' bination, construction and arrangement of parts illustrated in the accompanying drawings, and while I have shown therein a preferredembodiment I wish it to'be undera stood-that the same is susceptible oflmodp the spirit of my invention.

Inthe drawings fication and change without departing from Fig. 1 "s a fragmentary elevational of the upper portion of a heat insulate olicon tainer to which my improved stopper isap'f plied, the cup being v for the sake of clearnss.

Fig. 2 is a bottom plan view of im proved stopper or closurelookingupwardly partly broken away Fig. 1. w V i Fig.3 is a vertical transverse central sectional view taken on the line 3 3. of Fig. 2.

Fig. is a view similar to Fig. 2, but showing a modification in the arrangement of the rubber gasket. i

Fig. 5 is a vertical transverse sectional view on the line 5-5 of Fig. 4.

As will be seen in the drawings, my improved stooper or closure is applied to a re ceptacle 1 of the nature of a heat insulated jug, or the like. I do not wish, however, to be limited to the particular kind of receptacle to which this is applied, as my {invention is broad enough to be used in connection with any' receptac'le where such a stopper or closure is desired. More in detail my improved stopper comprises the main body member 2, having depending cylindrical sides 3, in which are rolled or otherwise j suitably formed threads 4, to be threaded on to similar threads at the same'when' in the positionshown in.

- formed in the upstanding outerportion of the the top of the member2. 'An inner hollow member 8 is arranged ininverted position, as shown in Fig. 3, w1th1n' body member 2.

- Projecting upwardly from member 8 is the cone-shaped portion 9, termmating in a cylindrical upstanding member 10, which when in serted'through opening 6 has its free edge 11 spun or otherwise suitably beaded down over the upstanding. flange 7, which latter, may,if desired, have the turned'back outer portion 12. other words, the cylindrical eXten- ,sion '10 of member 8 is passed throughthe central opening in the body member 2, and the flange of the latter and the free edge of the cylindrical member 10 are crimpedover so as to form a bead, or the'lik'e, as shown in'l igs. 3 and Any suitable arrangement of the parts in this connection would suffice, the main idea being to firmly secure the 'upstanding cylindrical extension of member 8 within body member 2, so that the same willbe securely fastened together and present a pleasing appearance.

Hollow member 8 is also formed withthe upstanding cylindrical wall 13, which may or may not as desired be fQrmed at its upper free edge with the outstanding flange 14.. In the fori'n shown in Figs. 2 and 3 a gasket 15 of rubber, fibre, or other insulating material, ispositioned and secured between the upper edge of cylindrical wall 13, and the adjacent top portion of body member 2. This gasket in this form of the invention-is, of course, placed in position, after which the hollow member 8 is secured,"as shown in Figf3, to clamp the gasket 15 between these parts. i "In Figs. 4' and 5 the gasket is not-positioned prior to assembling the parts as in 3, but after hollow member 81 has been secured in position'iwith-infbody member 2 lathe-latter form the gasket 15 isapplied to the eater-circumferenceor wall 13 after the stopper or closure has beenlfo'rmed, nem as will be apparent, be removed or returned tqposition as desired. Also in the form shown; in Fig, 3 an additional gasket, as shown 5, may be applied around the cylindrical wall 13 at any time the gasket loshows signs of deterioration. 7 In order apt-event the necessity ot'rem i-s g the entire stopper-,1 have provided to fit within the opening formed by theupstandiiig cylindrical extension 10 a cork member having a suitable metal top crimped aroundithe upper edges of the cork, as shown I V This cork 16of smaller diameter isof greatconvenience when it is desired to pour ice cold liquids from the jug or receptacle withouthaving the crackedice also flow out with tlie liquid. This provision ofa smaller s s- 'a s sp c e e the fii j sy f as jug orreceptacle, asjit prevents the atmos; 'pheric from flowing into the jug or recept'ac le to decrease its insulating efliciency 1 T-he cylindrical wall 13 of hollow member 8,-is o f ane ternal diametersubstantially the same or slightly less thanjthe internal diameterof the'neck ofthe jug or receptacle, so that when the stopper or closure is applied to the receptacle thehollow member swan formthestcpper for said necln As is readily seen in the drawing this construction affords the dead airspace 18 between the hollow member 8, whiehspace may onmay not,as; desired, be filled with groundcork or other suitable insulating material, as desired. Such filling is not necessary as the dead air space will itself function asan efficient insulation. A cup 19 -Icla-im is; i h I i l, e s 1- n ast rr r amain un-shar db dy is ii llfoprovided to be inverted and fit-snugly over, the threads 41: when the stopper is in place, thus renderingavailable for drinking,

or other purposes, the cup 19 when desired.

I Havmgnow described my inventlon what portion having a central opening through its upper face and a threaded circumferential skirt, a hollow member of smaller external diameter than the diameter of said skirt,
